WINDING ATTACHMENT FOE SEWING MACHINES.

Application filed October 12, 1921. Serial No. 507,248.

To all whom it may concern:

Be it known that we, MAX ALDERMAN and Gnoncn H. Enwnens, citizens of the United States, residing at Napa, in the county of Napa, and at Mill Valley, in the county of Marin, and State of California, respectively, have invented new and useful Improvements in finding Attachments for Sewing Machines, of which the following is a specification.

This invention relates to the manufacture of ornamental braid ribbons and the like, and especially to a machine for rapid and economical. manufacture thereof.

The object of the invention is to generally improve and simplify machines of the character described, and especially to provide a ribbon guiding and winding mechanism which may be readily attached to a standard form of sewing machine; said sewing machine completing the operation of manufacture by stitching or similarly fastening the ornamental material wound about the ribbon, as will hereinafter be described.

Further objects will hereinafter appear.

The invention consists of the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Fig. 1 is a perspective view of a sewing machine showing the application of the invention.

Fig. 2 is an enlarged detail sectional view of the ribbon feeding and winding mechanism.

Fig. 3 is a plan view of a section of braid wound and stitched by the mechanism illustrated in Fig. 1.

Fig. 4 is an enlarged cross section on line 4-4, Fig. 2.

Figure 5 is a central sectional view through the tube 12 showing the guiding arm 21 mounted therein.

Referring to the drawings in detail, and particularly to Fig. 1, A indicates in general a sewing machine of standard make, 2 the base, 3 the feed table, and 4: the foot or a guide through which the needle passes during the sewing operation. The sewing machine illustrated in the present instance is driven by an electric motor 5, and on the shaft of said motor is a stepped pulley 6, through which power is transmitted to a second stepped pulley, generally indicated at 7. Suitably secured to the base section 2 of the sewing machine is a plate 8. Forming a part thereof is a bearing bracket 9, and also forming a part thereof is a guide arm 10, on the upper end of which is mounted a roller 11, the function of which will hereinafter be described.

Secured in the bearing bracket 9 is a hollow shaft or sleeve 12, and journalled on one end thereof, as at 13, is the stepped pulley 7, previously mentioned. Formed in the pulley is a radially disposed slot 14:, and extending therethrough is a pin 15, which may be secured in any position desired by means of a thumb screw 16. The pin 15 is provided as a journal member and support for a spool 12"; this spool being secured against endwise movement on the pin by means of a washer 18, a spring 19 and a thumb screw 20; the spring 19 being employed for the purpose of exerting'a certain friction on the spool to retard turning moven'ient thereof during the winding operation, as will later be described.

Mounted interior of the stationary sleeve or shaft 12 and extending therethrough is a guide arm 21. This arm is preferably constructed of thin steel and one end is extended, as at 22, to form a support for the ribbon during the winding or application of the ornamental ribbon.

In actual practice a ribbon, such as indicated at 23, is passed through the sleeve 12, on one side of the blade or arm 21. It is then passed around the guide roller 11 and directed to the feeding and sewing mechanism of the machine A. A spool 17, containing yarn, metal braid, or other ornamental material, is next placed on thepin 15 and secured by means of the members indicated at 18, 19 and 20, said members securing the spool against endwise movement and frictional retarding rotation. The end of the yarn or other material carried by the spool is wound about the extending guide section 22 of the arm 21 and the ribbon 23 passing along one side thereof. The motor 5 when started will impart a rotary movement to the pulley 7 and as the spool 17 will rotate therewith, it can, readily be seen that the yarn or other material carried by the spool will be wound about the ribbon 23 as it is being pulled through the sleeve 12 by means of the feeding mechanism on the sewing machine. As the material is being ,2 fat) wound about the ribbon, it can readily be seen that the ribbon is advancing and that it will finally reach the table 3 where it will pass under the foot a and a stitch such as indicated at 2% will be applied; the stitch being employed for the purpose of securing the material wound about the ribbon as indicated at 25. The stitch may be formed along one edge or the ribbon as shown, or at any other point desired, such stitching being more or less essential as the ornamental yarn or other material wound about the ribbon might otherwise unravel or become displaced.

The provision of the tensioning means tow-it, the spring 19, is of considerable importance as it regulates the pull or strain on the yarn, as it is being wound about the ribbon 23 and the guide arm In other Words it determines the tightness with Which the member 25 is wrapped about the ribbon. The provision ol the guide arm 22 is also of great importance as it permits the yarn 25 to be tightly Wrapped about the ribbon without folding or collapsing the same during the winding op *ation. Another important feature of the invention is the provision of the stepped pulleys and '7. These are of course moved to form varying diametersas indicated at 26, 2? and 28, and to this extent regulate the speed of rotation. If it is desired to wrap the ribbon 23 fairly close, it is accomplished by driving the pulley 7 by placing the belt in the annular groove 28. If it is desired to increase the spacing of the wrap, it is accomplished by applying the belt to either the groove 26 or 27; the widest spacing being obtained when the groove 26 is employed. It should be remembered that the speed of the motor, the feed and the sewing mechanism of the sewing machine proper, remains constant, thus by vincreasing or decreasing the rotating speed of the pulley 7, it becomes possible to increase or decrease the spacing between the coils or wrapping applied to the ribbon 23.

The slotting of the pulley 7, as indicated at 14;, is another important feature as it permits radial adjustment of the spool 17 with relation to the guide arm 22, and it further permits application of smaller or larger spools as occasion may demand.

lVhile certain features of the present invention are more or less specifically illustrated, we wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claim, similarly that the materials and finish or" the several parts employed may be such as the experience and judgment of the manufacturer may dictate or varying uses may demand.

Having thus described our invention, what we claim and desire to secure by Letters Patent is- An attachment for sewing machines, comprising a bracket secured to the base thereof, a stationary hollow sleeve secured in the bracket, a pulley journaled on and rotatable about the said sleeve, a relatively thin i'lat guiding arm projecting horizontally through the sleeve with its broader side face extending in a vertical plane and having one end projecting therefrom, means for guiding a tape through the sleeve in a vertical position with its flat side face adja cent the inner fiat side of the guiding arm, and means for winding a strand of material about the tape.
